Asynchronous Transfer Mode (ATM) Networks

Paper Summary:

This paper looks at Asynchronous Transfer Mode (ATM) networks and switches including the problems associated with the old existing networks and the introduction of Broadband Integrated Networks. The paper also compares ATM networks with the traditional circuit and packet switching systems as well as discussing different categories of ATM switches and buffering schemes.

From the Paper:

"Asynchronous Transfer Mode is a digital technique for high speed switching. The unit of multiplexing and switching is a cell which comprises a short fixed length information packet with a fixed length header to carry signaling information. By offering access at the cell level, information from many sources with widely differing activity patterns and transmission rates can be interleaved on a single transmission link or switched through an ATM node. As in other packet switching environments capacity is used only when it is needed."
